The Language of Stucco
The cream-painted stucco facades of Belsize Park are among the most immediately recognisable elements of the neighbourhood's visual identity. Seen from the street on a clear day, the rows of stucco-fronted terrace houses with their Ionic porches, their elaborate cornices, and their continuous horizontal bands create a visual effect that is both impressive and intimate — grand enough to establish the social pretensions of the Victorian middle class that built them, domestic enough to remain habitable and humane in scale. The stucco tradition is one of the defining architectural languages of nineteenth-century London, and Belsize Park is one of its finest expressions.
The use of stucco as a facing material for brick buildings has a long history in English architecture, but its application to speculative residential development on a large scale was essentially a Victorian innovation. The Nash terraces around Regent's Park, completed in the 1820s, established the idiom that Victorian developers imitated and adapted throughout the remainder of the century: the brick structure faced in Portland cement render, painted white or cream to simulate the stone construction of more prestigious buildings, with moulded classical ornament in Coade stone or terracotta applied to the surface.
The Italianate style that dominates much of the stucco development in Belsize Park drew on the visual vocabulary of the Renaissance palazzo: round-arched windows, heavily moulded cornices, bold rustication at ground level, bracketed eaves. The style was popularised by Charles Barry's Reform Club in Pall Mall (1838) and quickly became the preferred idiom for upper-middle-class residential development across London. For the Victorian builder and his clients, the Italianate style represented a claim to the cultural heritage of Mediterranean civilisation — to a tradition of urbane, cultured domestic life that the English middle class aspired to embody in the new suburbs of North London.
Technical Challenges of Stucco
The maintenance of stucco facades has always been a technical challenge, and the Victorian stucco buildings of Belsize Park require periodic repainting and repair to maintain their original appearance. The cement render that forms the base of most stucco applications is prone to cracking as the building settles and as the render expands and contracts in response to temperature changes. Water penetration through cracks or poorly maintained joints can cause the render to blow — to detach from the underlying brickwork — requiring extensive repair work.
The traditional approach to stucco maintenance was to repaint the entire facade at intervals of perhaps five to ten years, touching up cracks and repairs as they appeared. The paints used historically were often lead-based, providing excellent adhesion and durability but raising obvious environmental and health concerns that have led to their replacement with modern water-based paints of varying quality and performance. The colour palette of the stucco neighbourhood — the particular quality of cream or off-white that Belsize Park's stucco facade presents — is partly a function of the paints used and partly a function of the weathering of the render beneath.
Contemporary conservation guidance emphasises the importance of using breathable, lime-based materials for the repair and maintenance of historic stucco facades, rather than the modern cement-based products that can trap moisture and accelerate deterioration. The adoption of appropriate maintenance techniques is one of the more technical challenges facing the owners of Victorian stucco properties in Belsize Park, requiring specialist knowledge and specialist contractors that are not always readily available or affordable.
The Conservation Implications
The stucco buildings of Belsize Park are covered by the conservation area designation that protects the neighbourhood's architectural character, and significant alterations to their external appearance require planning permission. The conservation area policies that govern alterations to stucco facades are designed to maintain the visual coherence of the streetscape — the uniformity of facade treatment, colour, and detailing that gives the stucco neighbourhood its distinctive character.
This can create tensions between the conservation interest in maintaining the historic character of the facades and the practical interest of building owners in maintaining their properties as economically and conveniently as possible. The requirement to use appropriate materials and techniques for stucco maintenance and repair — which are typically more expensive than the cheapest available alternatives — can be a significant burden for individual owners, particularly in a neighbourhood where property values are high but maintenance costs are also substantial.
The Stucco Streetscape Today
Walking through the stucco streets of Belsize Park today, it is possible to appreciate both the achievement of the Victorian builders who created this environment and the challenges of maintaining it for future generations. The best-maintained stucco terraces — their facades smooth and uniformly painted, their ornamental details intact, their ironwork railings and gates preserved — have a quality of civic elegance that is among the most refined in London. The less well-maintained examples — their facades cracked and discoloured, their ornamental details simplified or removed, their garden walls and railings replaced by cheaper alternatives — demonstrate what is at stake when the discipline of conservation maintenance is not maintained.
The stucco tradition is one of the elements that gives Belsize Park its distinctive character among London's inner neighbourhoods — a character of cream-painted urbanity, of civilised middle-class aspiration expressed in the language of Italian classicism, of architectural quality maintained across generations by the collective commitment of a community that values the environment it inhabits. The maintenance of this tradition is one of the neighbourhood's ongoing responsibilities to itself and to the city it is part of.
